[ovirt-users] 'Sanlock lockspace add failure' when trying to set up hosted engine 4.2 on existing gluster cluster

[Martin Sivak]

Hi Oliver,

which version of oVirt are you running?

The issue seems to be that correctly deployed hosted engine does not
have any storage available in the webadmin If I understand you
correctly. Is that right?

We used to require two separate storage domains in 4.1 and older
releases. One for hosted engine and one for the rest of the VMs. 4.2.1
changed that. So if you are running 4.1, just add another storage
domain [1] and the engine will finish the hosted engine initialization
automatically after that.

[1] https://www.ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_Engine/

See the paragraph: "Important: Log in as the admin at internal user to
continue configuring the Engine and add further resources. You must
create another data domain for the data center to be initialized to
host regular virtual machine data, and for the Engine virtual machine
to be visible. See "Storage" in the Administration Guide for different
storage options and on how to add a data storage domain."

Best regards

Martin Sivak
